DESCRIPTION
This product is specifically designed for use at power switching frequencies in excess
of 100 kHz. The product combines two Schottky-barrier diodes in a center-tap
configuration in a single package, simplifying installation, reducing heat sink
hardware, and the need to obtain matched components. The device is ideally suited
for demanding applications where small size and hermetically sealed package is
required. Common anode configuration also available.
